I'll help you determine the appropriate category when utilizing the Resolve difference in QuickBooks Online (QBO), PlumbingSecretary.

Make sure not to use your primary or source account as this will double or duplicate the amount. Instead, select the specific account where you want to offset the amount. For instance, if it's an expense, choose an expense account for offsetting. You can refer to this article for more details: Resolve the difference in a matched transaction.

I also recommend reaching out to your accountant for the best category to use and further guidance.

You can also reconcile your accounts to match your bank and credit card statements.

Comment back if you have anything else you want to clarify about handling categories. I'm ready to give the necessary information. Take care.
